Question

Which of the following is use of the v-t graph

(1 Point)

to find velocity at a given time

to find the displacement during a given time

to find acceleration of the body

all the above
​

Answer 1

Answer:

Instantaneous velocity at a given time-instant for a particle can be found from the y-intercept of its velocity-time graph.

From a particle's velocity-time graph, its average velocity can be found by calculating the total area under the graph and then dividing it by the corresponding time-interval.

For a particle with uniform acceleration, velocity-time graph is a straight line. Its average velocity is given by v

)/2. From the graph, this can be found by drawing the y-intercepts of initial and final velocities and then drawing the mid-point.

In the given graph, instantaneous velocity =v

Average velocity is found at E, i.e. mid-point of C and D. disposal meaning of velocity graph

Explanation:

hiThe area under the graph can be calculated by:

using geometry (if the lines of the graph are straight)

counting the squares beneath the line (particularly if the lines of the graph are curved)

Example

Calculate the total displacement of the object, whose motion is represented by the velocity-time please mark me down as a brainliest answer
